Rolling bearing forging is a common mechanical part, which is processed by metal materials under high temperature and high pressure through forging process. Compared with other manufacturing methods, rolling bearing forgings have the advantages of higher performance, longer life and more stable quality. In this paper, the forging of rolling bearing and its manufacturing process will be described in detail.
First of all, the manufacturing process of rolling bearing forgings mainly includes: bar cutting, heating, forging, sampling, quenching and processing heat treatment and other links, of which the forging process is the key production step. In the forging process, after the ingot is preheated, the ingot is sent to the forging press for hammering and extrusion, so that the ingot is plastic deformed and gradually formed into the required rolling bearing forging. In the entire manufacturing process, strict control of temperature, pressure, molding speed and other parameters can ensure the physical properties and dimensional accuracy of rolling bearing forgings. The process of sampling, quenching and processing heat treatment at the back is to improve the strength and hardness of rolling bearing forgings, and to ensure their high wear resistance and life.
Secondly, the advantage of rolling bearing forgings is that compared with other manufacturing methods such as casting and pressure processing, it has the following outstanding advantages:
No internal defects: in the forging process, the thermal deformation of the material is in a good plastic state, which can fully eliminate the internal defects, so that the leakage is less, and the vertical deformation is good.
Better physical properties: the strength, toughness, compressive strength and torque resistance of rolling bearing forgings are better than those of cast parts, cast and forged connected parts and forged billets.
Higher working life: Due to the longer fatigue life of rolling bearing forgings after they are made, it is not easy to deform or fail, and has extremely important application prospects in the field of machinery industry.
Finally, with the increasingly mature modern automated production technology and people’s pursuit of product quality, rolling bearing forgings are widely used in automotive, construction machinery, aerospace, oil and gas and metallurgy and other fields. As an important mechanical part, rolling bearing forgings have the advantages of high cost but stability and reliability, which can help improve the performance and efficiency of mechanical equipment.
